Timing and Performance Options

Chapter 18. Nping Reference Guide

Timing and Performance Options

--delay <time> (Delay between probes)

This option lets you control for how long will Nping wait before
sending the next probe. Like in many other ping tools, the default
delay is one second.
<time> must be a positive
integer or floating point number. By default it is specified in
seconds, however you can give an explicit unit by appending
ms for milliseconds, s for seconds,
m for minutes, or h for hours
(e.g. 2.5s, 45m, 2h).

--rate <rate> (Send probes at a given rate)

This option specifies the number of probes that Nping should send
per second. This option and --delay are inverses;
--rate 20 is the same as
--delay 0.05. If both options are used, only the
last one in the parameter list counts.
